[A CASE OF MISIDENTIFIED SYNCHRONOUS COLON CANCER]

CSERNI Gábor, BORI Rita, OLÁH Csaba, HAUSINGER Péter, TUSA Magdolna, MARKÓ László, SVÉBIS Mihály

[INTRODUCTION - Synchronous colorectal cancers are not uncommon, therefore, total colonoscopy is indicated even in cases of distally located large bowel carcinomas. CASE REPORT - An 84-year-old man had emergency surgery because of bowel obstruction and a node-negative carcinoma of the sigmoid colon was removed according to Hartmann. Before the reconstruction of bowel continuity, colonoscopy revealed a relatively small polypoid tumour in the right colon, unsuitable for colonoscopic polypectomy. Two localization clips were then inserted at the site of the endoscopic biopsy that later resulted in the diagnosis of adenocarcinoma. At the time of the reconstruction surgery, an appendectomy was also performed and, though the clips were not found, the polypoid tumour was removed through appendectomic orifice. The polyp thus removed, however, proved to be an adenoma. A repeated colonoscopy and biopsy confirmed both the localization clips and the malignant nature of the remaining right-sided lesion, which was finally removed with right hemicolectomy. CONCLUSION - Anatomic localization of rightsided colon cancers by colonoscopy is often imprecise. The correct identification of a malignant tumour may be compromised by a nearby benign lesion. If a lesion was labelled by some means, the localization sign should be identified both intraoperatively and during the gross pathologic work-up, asking for external help (e.g., radiology in case of a metal clip) if necessary.]

[MYELODYSPLASTIC SYNDROMES - NEW THERAPEUTIC OPTIONS]

GADÓ Klára

[Myelodysplastic syndrome is a heterogeneous group of acquired clonal disorders of the haematopoietic stem cell characterized by ineffective haematopoiesis, peripheral cytopenia, and a high risk of progression to acute leukaemia. It is a common malignant disease with an increased incidence in the elderly population. Classification is based on a 1999 WHO recommendation, in which morphological features as well as clinical and cytogenetic characteristics are taken into account. Combined with the International Prognostic Scoring System (1997), it is suitable to predict prognosis and response to therapy. Clinical features include symptoms caused by anaemia, infections, and bleeding. Diagnosis is based on peripheral cytopenia and dysplastic morphology, as well as normal or increased cellularity in the bone marrow, with more than 10% of dysplastic cells. The verification of cytogenetic abnormalities is important both for confirming the diagnosis and predicting the prognosis. When designing the treatment strategy, it is essential to take the risk of leukaemia into account. On the other hand, the general state of the patient and the presence of accompanying diseases should also be considered. The goal of the treatment is to increase cell count and to decrease transfusion requirement, eventually to improve quality of life. Supportive therapy is an essential part of the management. In addition, growth factors, immunosuppressive and immunomodulatory agents, low-dose chemotherapy may be applied. Today, cure can only be achieved by allogenic stem cell transplantation. Recent findings in the epigenetic intracellular regulation allowed the definition of new therapeutic targets to develop drugs such as inhibitors of DNA methyltransferase and histone deacetylase.]

[THE ROLE AND METHODS OF IMPROVING INSULIN SENSITIVITY AND BETA-CELL FUNCTION IN TYPE 2 DIABETES]

GYIMESI András, TÁRNOK Enikő, TAYBANI Zoltán

[Increased knowledge on the pathogenesis of type 2 diabetes has considerably transformed the principles and practice of treatment. Insulin resistance and beta-cell dysfunction, the two main components of the pathogenesis both play a role in the conversion of normal glucose metabolism, through impaired glucose tolerance, into type 2 diabetes. Decreased insulin sensitivity, with or without beta-cell dysfunction, is present in the vast majority cases, therefore, its treatment is essential. Physical activity is known to improve insulin sensitivity. The primary action of the recommended first-line pharmacological agent metformin is the inhibition of hepatic glucose production but it also moderately stimulates muscle glucose uptake. Glitazones are insulin sensitizers that increase glucose uptake in muscle and adipose tissue and moderately decrease hepatic glucose production. Some evidence suggests that α-glucosidase inhibitors and also certain insulin secretagogues can improve the effect of insulin. Early detection of the pathologic state and an efficient treatment to improve both insulin sensitivity and beta-cell function are essential in order to slow the progression and prevent the development of complications in type 2 diabetes.]

EEG-based connectivity in patients with partial seizures with and without generalization

DÖMÖTÖR Johanna, CLEMENS Béla, EMRI Miklós, PUSKÁS Szilvia, FEKETE István

Objective - to investigate the neurophysiological basis of secondary generalization of partial epileptic seizures. Patients and methods - inter-ictal, resting-state EEG functional connectivity (EEGfC) was evaluated and compared: patients with exclusively simple partial seizures (sp group) were compared to patients with simple partial and secondary generalized seizures (spsg group); patients with exclusively complex partial seizures (cp group) were compared to patients with cp and secondary generalized seizures (cpsg group); the collapsed sp+cp group (spcp) was compared to those who had exclusively secondary generalized seizures (sg group). EEGfC was computed from 21-channel waking EEG. 3 minutes of waking EEG background activity was analyzed by the LORETA Source Correlation (LSC) software. Current source density time series were computed for 23 pre-defined cortical regions (ROI) in each hemisphere, for the 1-25 Hz very narrow bands (1 Hz bandwidth). Thereafter Pearson correlation coefficients were calculated between all pairs of ROI time series in the same hemisphere. Z-scored correlation coefficients were compared at the group level (t-tests and correction for multiple comparisons by local false discovery rate, FDR). Results - Statistically significant (corrected p<0.05) EEGfC differences emerged at specific frequencies (spsg > sg; cpsg > cp), and at many frequencies (sg > spcp). The findings indicated increased coupling between motor cortices and several non-motor areas in patients with partial and sg seizures as compared to patients with partial seizures and no sg seizures. Further findings suggested increased coupling between medial parietal-occipital areas (structural core of the cortex) and lateral hemispheric areas. Conclusion - increased inter-ictal EEGfC is associated with habitual occurrence of secondary generalized seizures.

[Results of breast cancer screening and clinical mammography at the Kenezy Breast Center, Debrecen between 2002-2003]

SEBŐ Éva, SARKADI László, KOVÁCS Ilona, VAJDA Olga

[INTRODUCTION - Breast cancer screening has been started in January 1. 2002. in Hungary in the course of the National Health Program. Breast cancer is the main cause of death among women’s malignant tomors, and the aim of the project is to reduce this mortality. The chance of survival is highly increased by the early detection of the disease. Kenezy Breast Center was connected to this project. PATIENTS AND METHODES - Females between 45-65 years without symptoms participated in the project. Paralel to this women with symptoms, sometimes with palplable masses were clinically examined. Screening mammography films were read by two radiologists and the complementary examinations of the breast and the axillary lymph nodes - ultrasonography, guided biopsy (FNAB, core biopsy) - were performed always by the same doctor. Results of the two projects were compared. RESULTS - The incidence of malignant breast cancer was 4‰ in the screening and 1,5% in the clinical group. 46.5% of the malignant breast cancers revealed by the clinical examinations was diagnosed in the group of women between the age of 45 to 65 years. This is the age when most women are involved in the screening program. 7.3% of the tumors was diagnosed in the 40- 44 year age-group and 11.3% among women aging 66-77 years. The rate of malignant tumors smaller than 1.5 cm was 49.1% according to screening records and 36% in the clinical trial. In both groups, tumor size of 1.5 cm proved to be a critical limit regarding to the development of metastases, mainly in the axillary region. Above this size, metastases were more frequent. CONCLUSIONS - Both breast screening program and clinical exams are of great significance. Based on the data obtained during two years, authors found that women below the age of 40 and above the age of 65 should also be involved in the screening program. Detection of breast tumor is possible at an early stage by screening. In the case of small tumors (smaller than 1.5 cm) the development of axillary metastases is less likely than in the case of larger ones. The lack of metastases in the axillary lymph nodes offers better prognosis according to the published scientific data, which reinforces the importance and necessity of the screening programs.]

[The effect of whole body electrostimulation for the pelvic floor muscles ]

ARANYNÉ Molnár Tímea, NAGY Edit, DOMJÁN Andrea, FEKETE Zoltán, SURÁNYI Andrea, BÓDIS József

[The aim of the study: Few studies research the effects of trunk stabilizer muscle strengthening on pelvic floor dysfunctions. We assessed a new core strengthening method on the pelvic floor muscles. Material and method: Female patient (70 years) with stressincontinence and low back pain received the Whole Body Electric Muscle Stimulation for 10 weeks (2x25 minutes/week). The EMG (for the conditioning ability of pelvic floor muscle such as maximal isometric contraction, dynamic endurance and relaxation values), urodynamic assessment, introitus and the transabdominal ultrasound were used before and after training. Results: The patient’s the stressincontinence, low back pain and the conditioning ability of pelvic floor muscles improved. The urodynamic and ultrasounds values showed improvement in functions of the bladder neck and deep abdominal muscle. Conclusion: This method would increase the trunk stabilization and pelvic floor muscle strength of the eldery age group, which might decrease the prevalence of urinary incontinence.]

[Results of non-operative pathological breast diagnostics - One year experience at the Bács-Kiskun County Teaching Hospital]

CSERNI Gábor, AMBRÓZAY Éva, SERÉNYI Péter, BORI Rita, LŐRINCZ Margit, LÓRÁND Katalin

[INTRODUCTION - Non-operative cytological and histopathological assessment of breast lesions are part of the triple (physical, imaging and pathologic) diagnostic approach and allow a more precise planning of surgical procedures. Both methods have advantages and disadvantages; currently, core biopsy is believed to be more efficient in reaching the diagnostic target. PATIENTS AND METHODS - Breast specimens with a histological diagnosis at the Department of Pathology of the Bács-Kiskun County Teaching Hospital were analysed for their preoperative pathology, using the conventional C1-5 and B1-5 diagnostic categories. RESULTS - 295 cytology and 130 core needle biopsy cases were analysed. The rate of non diagnostic (C1 and B1) material was higher for cytology (0.18 versus 0.08 in general; 0.09 versus 0.01 for malignant cases). The rate of cases with an uncertain diagnostic category (C3 and C4 or B3 and B4) was also higher for the cytology specimens (0.24 versus 0.07). False-negative and false-positive cases were rare, but still more frequent among cytology specimens. CONCLUSION - Core needle biopsy performs better than fine needle aspiration cytology in the establishment of a nonoperative diagnosis at our institution. Despite these results, cytology continues to be the first diagnostic choice, because of its relatively low costs.]

[Breast core needle biopsies yielding uncertain results - Experience at the complex mammographic screening unit in Kecskemét]

AMBRÓZAY Éva, BORI Rita, LŐRINCZ Margit, LÓRÁND Katalin, CSERNI Gábor

[INTRODUCTION - On occasion core biopsies yield an inconclusive (B3 or B4) result in the triple diagnostics of breast lesions. These cases may turn to be malignant in the operation specimen. This study evaluates the value of B3 and B4 diagnoses and the consequences of these diagnoses. MATERIALS AND METHODS - Core needle biopsies were generally taken under imaging guidance with an automatic gun using G14 gauge needles. They were evaluated using internationally and nationally accepted categories from B1 to B5. The analysis was based on data collected between 2000 and March 2005. RESULTS - Of the 663 core needle biopsy specimens 31 (4.7%) were classified as B3 and 22 (3.3%) as B4. Specimens were more often fragmented in the latter category (a rate of 0.64 as compared with a rate of 0.26). Patients with a B3 diagnosis were operated on in 23 cases, eight of which turned to be malignant (0.35). B4 diagnoses were followed by operations in 21 cases and were found to be malignant on 19 occasions (0.9). Whenever a B4 diagnosis was associated with radiological findings of malignancy (category 5 on mammography and/or ultrasound) the cases unanimously proved to be malignant. The same association with B3 diagnoses yielded malignancy in a rate of only 0.67. CONCLUSION - Both B3 and B4 diagnoses represent an indication for operation. Our experience suggests that B4 diagnoses when coupled with a radiological opinion of malignancy can be candidates for definitive (therapeutic breast conserving) surgery whereas B3 diagnoses require diagnostic excisions.]
